DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Reference will now be made in detail to embodiments of the present disclosure, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the like elements throughout the several views. In this regard, the present embodiments may have different forms and should not be construed as being limited to the descriptions set forth herein. Accordingly, the embodiments are merely described below, by referring to the figures, to explain aspects of the present description. Terms used herein are for descriptive purposes only and are not intended to limit the scope of the disclosure. The terms “comprises” and/or “comprising” are used to specify the presence of stated elements, steps, operations, and/or components, but do not preclude the presence or addition of one or more other elements, steps, operations, and/or components. The terms “first,” “second,” and the like may be used to describe various elements, but do not limit the elements. Such terms are only used to distinguish one element from another. These and/or other aspects become apparent and are more readily appreciated by those of ordinary skill in the art from the following description of embodiments of the present disclosure, taken in conjunction with the accompanying drawings.

The words and phrases used herein should be understood and interpreted to have a meaning consistent with the understanding of those words and phrases by those skilled in the relevant art. No special definition of a term or phrase, i.e., a definition that is different from the ordinary and customary meaning as understood by those skilled in the art, is intended to be implied by consistent usage of the term or phrase herein. To the extent that a term or phrase is intended to have a special meaning, i.e., a meaning other than the broadest meaning understood by skilled artisans, such a special or clarifying definition will be expressly set forth in the specification in a definitional manner that provides the special or clarifying definition for the term or phrase.

For example, the following discussion contains a non-exhaustive list of definitions of several specific terms used in this disclosure (other terms may be defined or clarified in a definitional manner elsewhere herein). These definitions are intended to clarify the meanings of the terms used herein. It is believed that the terms are used in a manner consistent with their ordinary meaning, but the definitions are nonetheless specified here for clarity.

A/an: The indefinite articles “a” and “an” as used herein mean one or more when applied to any feature in embodiments and implementations of the present disclosure described in the specification and claims. The use of “a” and “an” does not limit the meaning to a single feature unless such a limit is specifically stated. The term “a” or “an” entity refers to one or more of that entity. As such, the terms “a” (or “an”), “one or more” and “at least one” can be used interchangeably herein.

At least: As used herein in the specification and in the claims, the phrase “at least one,” in reference to a list of one or more elements, should be understood to mean at least one element selected from any one or more of the elements in the list of elements, but not necessarily including at least one of each and every element specifically listed within the list of elements and not excluding any combinations of elements in the list of elements. This definition also allows that elements may optionally be present other than the elements specifically identified within the list of elements to which the phrase “at least one” refers, whether related or unrelated to those elements specifically identified. Thus, as a non-limiting example, “at least one of A and B” (or, equivalently, “at least one of A or B,” or, equivalently “at least one of A and/or B”) can refer, in one embodiment, to at least one, optionally including more than one, A, with no B present (and optionally including elements other than B); in another embodiment, to at least one, optionally including more than one, B, with no A present (and optionally including elements other than A); in yet another embodiment, to at least one, optionally including more than one, A, and at least one, optionally including more than one, B (and optionally including other elements). The phrases “at least one”, “one or more”, and “and/or” are open-ended expressions that are both conjunctive and disjunctive in operation. For example, each of the expressions “at least one of A, B and C”, “at least one of A, B, or C”, “one or more of A, B, and C”, “one or more of A, B, or C” and “A, B, and/or C” means A alone, B alone, C alone, A and B together, A and C together, B and C together, or A, B and C together.

Comprising: In the claims, as well as in the specification, all transitional phrases such as “comprising,” “including,” “carrying,” “having,” “containing,” “involving,” “holding,” “composed of,” and the like are to be understood to be open-ended, i.e., to mean including but not limited to.

Embodiments: Reference throughout the specification to “one embodiment,” “an embodiment,” “some embodiments,” “one aspect,” “an aspect,” “some aspects,” “some implementations,” “one implementation,” “an implementation,” or similar construction means that a particular component, feature, structure, method, or characteristic described in connection with the embodiment, aspect, or implementation is included in at least one embodiment and/or implementation of the claimed subject matter. Thus, the appearance of the phrases “in one embodiment” or “in an embodiment” or “in some embodiments” (or “aspects” or “implementations”) in various places throughout the specification are not necessarily all referring to the same embodiment and/or implementation. Furthermore, the particular features, structures, methods, or characteristics may be combined in any suitable manner in one or more embodiments or implementations.

Exemplary: “Exemplary” is used exclusively herein to mean “serving as an example, instance, or illustration.” Any embodiment described herein as “exemplary” is not necessarily to be construed as preferred or advantageous over other embodiments.

Wearable devices can be worn on user's wrist and offer convenient access in very versatile situations and environments. Identification tags including barcode, QR code, or RFID are highly abundant in multiple enterprise environments and require high frequency of interactions to maintain proper documentation and workflow. Conventionally, most handheld scanners require the user to be constantly handling bulky or heavy equipment for a long period of time.

According to one embodiment of the present disclosure, a wearable device is provided. In particular, for exemplary purpose only, the wearable device in the medical field will be described herein in detail. However, of course, the present disclosure is not limited thereto.

The wearable device acting as a handheld scanner can be a useful tool to record and maintain a patient's condition. For instance, whenever a user takes medication, the user can read a barcode label on a medicine container with the wearable device. Thus, a memory coupled to the wearable device can store detailed information of time, location, frequency, and contents therein so that it enables to keep track of the patient's medical record.

Furthermore, the wearable device can provide an alarm for how often the user needs to take one or more doses of a plurality of mediccations, over a span of hours and days, and the wearable device can keep track of times the dosages are taken. Thus, where a person is required, for reasons of health, to take a variety of medications at differing times of the day or night, then it can be easily performed with the wearable device according to the present disclosure with a simple program.

The wearable device as a handheld scanner is convenient in regards to aiming, handling, and repositioning the barcode scanner light to insure that all angles and ranges are available for the user to scan with ease. The conversion between a wearable device and a handheld one allows the user to carry the scanner hands-free without the need to hold it, as well as have quick access to it in any moment of need.

With reference now to FIG. 1, there is depicted a block diagram of two (2) independent computing devices “10” and “20,” and two (2) wearable devices 100 and 200 that are presented for only exemplary and explanatory purposes as similar pairs of a first computing device 10 and a first wearable device 100, and a second computing device 20 and a second wearable device 200. For the purposes of this application, a “computing device” is to be interpreted broadly as including among others standard personal computers, smart phones, notebooks, tablets, “iPod”, “iPad”, similar Android or iOS devices, and any type of wearable device having user interface. Obviously, more than two independent computing devices can be employed in accordance with the present disclosure.

First and second wearable devices 100 and 200 are now described in greater detail in which the same units digits and tens digits are used to identify the same components in each wearable device 100 or 200. However, only first wearable device 100 is described further herein, but it is understood that second wearable devices 200 have the same type of components that are identified by the same units digits and tens digits.

Referring to FIG. 1, the first wearable device 100 can be comprised of at least one of a wrist band unit 110, a network unit 120, a display assembly 130, a control unit 140, a reader 150. Wrist band unit 110 is designed to be worn on the wrist of a user. Wrist band unit 110 is described in greater detail with respect to FIGS. 2A, 2B, 2C, 2D, 3A, 3B, 3C, and 3D.

Wrist band unit 110 can be made of any flexible material, preferably a polymer plastic, but could also include a standard plastic, leather, and a shaped metal band or linked metal band. In some embodiments, wrist band unit 110 can have a length adjustable feature. For example, each ends of wrist band unit 110 can include a conventional detachable metal/plastic block (not shown) or a conventional magnetic block (not shown) to adjust the length.

Network unit 120 is configured to communicate with other devices. Network unit 120 can be, for instance, disposed at display assembly 130. Display assembly 130 can include control unit 140 as well. Display assembly 130 can include at least one reader 150. Reader 150 is configured to scan either barcode, QR, or a Radio Frequency Identification (“RFID”). Reader 150 will be described later in detail.

Network unit 120 can be disposed at display assembly 130. Operationally, network unit 120 is comprised of at least one of a wireless and/or Bluetooth communications transceiver unit 122, a NFC (Near Field Communication) unit 124, an internet connection unit (not shown), or a Global Positioning System (GPS) unit (not shown). In general, network unit 120 is a communication unit that can wirelessly communicate with first computing device 10. For instance, network unit 120 can communicate with the first computing device 10 using a Bluetooth or internet connection unit (not shown) including Long-Term Evolution (LTE) or Wifi. Network unit 120 can also communicate with another wrist band unit 210 within a second wearable device unit 200, for instance, by using an NFC device.

For conventional practical reasons, network unit 120 can utilize high frequency electromagnetic radiation, but it is also possible to use, for example, a line-of-sight mechanism such as infrared signals (as used in many television remotes), or to use sonar or lower frequency radiation. In addition, in an alternative embodiment, a communications unit can include a unit for wirelessly accessing the Internet, or other communication network, and/or to a satellite.

Display assembly 130 can be mounted on wrist band unit 110. Display assembly 130 can include a conventional LCD or LED display, and can include a touchpad or panel. Control unit 140 includes a processor 142 programmed and connected to deliver commands and receive information from display assembly 130, and network unit 120.

Reader 150 is coupled to control unit 140. Reader 150 is configured to read at least one of a barcode, a QR code, or RFID.

Reader 150 can be a barcode reader. A barcode is an optical machine-readable representation of data relating to the object to which it is attached. Barcodes systematically represent data by varying the widths and spacings of parallel lines, and may be referred to as linear or one-dimensional (1D). Later two-dimensional (2D) codes were developed, using rectangles, dots, hexagons and other geometric patterns in two dimensions, usually called barcodes although they do not use bars as such Barcodes can be scanned by reader 150, optical scanners.

Reader 150 can be a QR code reader. QR code (abbreviated from Quick Response Code) is the trademark for a type of matrix barcode (or two-dimensional barcode). A barcode is a machine-readable optical label that contains information about the item to which it is attached. A QR code can, for instance, use four standardized encoding modes (numeric, alphanumeric, byte/binary, and kanji) to efficiently store data.

Reader 150 can be a Radio Frequency Identification (RFID) reader having an antenna, and an image capture device coupled to at least one of the readers and the antennae. Radio Frequency Identification (RFID) systems are of use in many different areas. For example, RFID systems can be used to track goods as they move throughout the supply chain. A RFID system includes reader 150, at least one RFID tag affixed to an item of interest and, a computer system coupled to reader 150 to process data. RFID tags include memory that stores data concerning the item to which the RFID tag is attached. For example, an RFID tag may be attached to a product or a product's packaging such as the packaging for a drill. The RFID tag attached to the drill's packaging can store a product identification code that uniquely identifies the item. Reader 150 sends interrogation signals to RFID tags and receives responses from the RFID tag. Reader 150 can be handheld. Reader 150, depending on the needs of the end user and the capability of the RFID tags, can read data from the RFID tag and/or write information to the RFID tag. In the example discussed above, reader 150 can be used to read the product identification code from the RFID tag attached to the packaging of the drill. The computing device receives data from reader 150 and can then store, process or otherwise use the collected data. In the example discussed previously, the computer system can receive the product identification code from reader 150 and then use the product identification code in conjunction with a database program to retrieve pricing information for the drill. The pricing information can be sent back to a device that is part of the computer system. For example, the pricing information may be sent to a point-of-sale (POS) system. While typical RFID systems, with handheld or a fixed reader 150, are ideal in many circumstances, but they have drawbacks. For example reader 150 can be cumbersome to use. Also, RFID systems require a user to point the reader 150 at different tags. The repetitive nature of pointing and activating reader 150 can be tiring to individual users. Regarding RFID, the U.S. non-Provisional application Ser. No. 10/931,462, filed 31 Aug. 2004, is incorporated by reference herein in its entirety.

With reference to FIGS. 2A and 2B, first wearable device 100 is depicted in greater detail in a presently preferred embodiment. FIG. 2A is a perspective view of the wearable device 100 in a first mode according to one embodiment of the present disclosure. FIG. 2B is a perspective view of the wearable device 100 in a second mode according to one embodiment of the present disclosure.

A wearable device 100 includes wrist band unit 110 and display assembly 130 having a reader 150.

Wrist band unit 110 has a length adjustable feature 110 a. Wrist band unit 110 can be fully closed and have certain rigid areas therein which can be adjusted for a length to accommodate a handle.

In another embodiment, reader 150 can detachably attached to wrist band unit 110. For exemplary purposes, although only one single reader 150 is described in FIG. 2A, a number of the reader 150 is not limited thereto. For exemplary purposes only, reader 150 can be positioned to face along a tangential direction A to a curve made by wrist band unit 110. The tangential direction A is described in FIGS. 2A and 2B with dotted lines. However, the location of reader 150 on display assembly 130 is not limited thereto. Reader button 150 a is electrically coupled to reader 150. Thus, when the user pushes reader button 150 a, reader 150 works a predetermined task. For exemplary purposes only, reader button 150 a is described as located at first wrist band unit 110, the location thereof is not limited thereto. For instance, reader button 150 a can be located on display assembly 150, second wrist band unit 110, or inside wrist band unit 110. Wrist band unit 110 can have a wrist band opening 110 b corresponding to reader 150 so that it is ensured that reader 150 has a line of sight to an object.

Referring to FIG. 2C, reader 150 can be activated by a user's finger F with a transparent touch digitizer in front of reader 150. Referring to FIG. 2D, reader 150 can include a touch digitizer 151 and reader device 152. Reader device 152, for instance, can be a scanner. Touch digitizer 151 can activate reader 150 by the user's tapping, long press, or swiping.

Reader 150 standing alone or attached to display assembly 150 can be used independently as a handheld scanner. Reader 150 can be a scanner so that wearable device 100 can be converted to a handheld scanner. Since wrist band unit 110 can act as a holder for the detachable display assembly having the scanner, the wrist band unit 110 can be set back at different angles to change a scan angle.

FIGS. 3A-3D illustrate various embodiments of combinations of first wrist band unit 111 and second wrist band unit 112. Referring to FIG. 3A, first wrist band unit 111 and second wrist band unit 112 are connected to each other and form a circular shape.

As the user wearing first wearable device 100 walks, first dependent screen 172 shows an animated running man icon 172A. The animated running man icon can be programmed to show a running animation corresponding to the user's walking speed.

Second dependent screen 174 can display an audio player. Display assembly 130 can be comprised of either a touchpad or a touch screen to receive an input from the user. For example, when display assembly 130 is comprised of a touchpad, the user can tap the screen with one finger to play or pause the audio player.

Third dependent screen 176 is configured to show a list of schedules. A current schedule 176A can appear larger than a previous schedule 176B. Third dependent screen 176 can be configured to display a list of other various activities including performances the first wearable device 100 has operated.

Fourth dependent screen 178 is configured to display notification and any recent updates from a acti-block 214 (see FIG. 21). For example, fourth dependent screen 178 includes an e-mail icon 178A. When the user touches e-mail icon 178A, fourth dependent screen 178 shows the e-mails the user has received.

When the user desires to switch a screen from home screen 170 to first dependent screen 172, the user can touch and drag his finger from left to right on display assembly 130. After the user switches the screen, first dependent screen 172 becomes visible, and the other screens 170, 174, 176, and 178 become invisible or hidden, as depicted in FIG. 20B. The user can return back to home screen 170 by dragging his finger on display assembly 130 in a direction of arrow 172B. Display assembly 130 can be configured to include a setting that switches a pending screen to either home screen 170 or any specific dependent screens 172, 174, 176, and 178. For example, display assembly 130 can be configured to switch screens according to the type of inputs by fingers. If the user taps the screen twice with two fingers, then display assembly 130 can switch the screen back to home screen 170. If the user taps the screen thrice or three times with three fingers, then display assembly 130 can switch the screen to third dependent screen 176. If the user taps the screen four times with three fingers, then display assembly 130 can switch the screen to fourth dependent screen 178. Although the exemplary of the present screen displays of the disclosure have been disclosed for illustrative purposes, those skilled in the art will appreciate that various modifications, additions and substitutions are possible, without departing from the scope and spirit of the disclosure.

In summary, to switch modes of home screen 170, the user drags his or her finger from top downwardly on display assembly 130 and obtains second dependent screen 174A, as depicted in FIG. 20C. Second dependent screen 174 becomes visible, and other screens 170, 172, 176, and 178 become hidden or invisible. The user can return back to home screen 170 by dragging his finger on display assembly 130 in a direction of arrow 174A. For example, in a preferred embodiment, as depicted in FIG. 20A, different screen can be selected from a pending screen by swiping either vertically or horizontally in a direction of an arrow 170A.

With reference now to FIG. 21, a diagrammatic illustration of an interface screen between first computing device 10 and first wearable device 100 (see FIG. 1) is illustrated. An interface of acti-block computer program includes a plurality of buttons on the screen of computing device 10. Acti-block computer program provides a Social Network Service which is a platform to build social networks or social relations among people who, for example, share interests, activities, backgrounds, or real-life connections. FIG. 21 depicts a user interface of acti-block computer program screen on computing device 10 such as a smart phone or iPod. Acti-block computer program interface includes a logo and home page button 202, a biographic information button 204, a photo album button 206, a message button 208, a grouping information button 210, a notification button 212, acti-block 214, and a statistics button 216, a status update button 218, and control panel tab 220.

Logo and home page button 202 shows a logo of a company and when pushed or tapped by the user, switches the screen to a home screen. Biographic information button 204 includes a link to a profile information of the user. Photo album button 206 has a link to a plurality of photographs and photographic information that the user or his or her friends have uploaded or shared. Message button 208 is conventionally configured to send and receive a message to a friend.

Grouping information button 210 includes conventional algorithms based on tags or common factors. For example, when the user updates his profile or photos, he or she can create and update related tags as well. If the user is interested in a basketball game, grouping information button 210 can display any relevant information related to the basketball game as a result of a search based on the tags. Posting updates button 210 shows any updates the user or the user's friends made recently. Notification button 212 shows any new message from another compatible user, an email invitation, a listing of friends, and updates on comments. Acti-block 214 is configured to update data according to inputs from first wearable device 100. Acti-block 214 is configured to have a calendar-like function which displays dates.

Acti-block 214 is configured to be connected and be updated by activities of first wearable device 100. For example, if the user wearing first wearable device 100 runs 4 miles, then the distance information received from first wearable device 100 is transferred to computing divide 10 and acti-block 214 is updated with such information automatically. In this way, acti-block 214 can contain any activity information received from first wearable device 100. Such activity information can contain calories, kind of food the user had, budget, list of groceries, profile of friends the user met and any other activities conducted on daily bases. For example, the user can scan several items the user bought with a help of a scanner disposed in first wearable device 100 and first wearable device 100 can calculates the price of the items bought and deduct the price of the items from the predetermined monthly budget. Thus, first wearable device 100 can calculate and transfer the information to the acti-block computer program such that the actiblock computer program can display the information such as remaining available funds for the month. Statistics button 216 is configured to show statistics of activities performed in the acti-block computer program. For instance, statistics button 216 can show the calories the user burned for the last one month, a distance the user has walked for the last one month or a monthly budget history calculating and displaying a budge surplus and deficit based on the information the first wearable device 100 scanned. Status update button 218 shows any new updates. Control panel tab 220 can be configured to create new tabs according to the user's needs such that the user can control and organize his events. A support tab 222 can be configured to display any contact information of the user's friends, any help message, problem reports or the like in a conventional manner.

According to a predetermined setting, first wearable device 100 can transfer information either to another second wearable device 100 (see FIG. 1) or to computing device 10. With reference now to FIG. 22, a subroutine for determining where to transfer input information is depicted. The subroutine begins at a start terminal 310 and proceeds to a step 320 where input information and data to first wearable device 100 is obtained. From step 320, the process proceeds to a decision step 330 where it is determined if the type of input is for an NFC device. If the input is for an NFC device, then the program proceeds to a decision step 340 where a determination is made if a second NFC device is detected, such as second wearable device 100 (FIG. 1). If it is not detected, then the program repeatedly loops to the top of decision step 340 until the second NFC device is detected. However, if decision step 340 determines that an appropriate NFC device is detected, than the program proceeds to step 350 in which the information is transferred to the second NFC device, and then the program terminates in terminal 360. However, if decision step 330 determines that the input is not for an NFC device, then the program branches to a decision step 370 where it is determined if the type of input is for a Bluetooth device. If the input is for a Bluetooth device, then the program proceeds to a decision step 380 where a determination is made if a Bluetooth device is detected, such as computing device 10 (FIG. 1). If it is not detected, then the program repeatedly loops to the top of decision step 380 until the Bluetooth device is detected. However, if decision step 380 determines that an appropriate Bluetooth device is detected, then the program proceeds to step 390 in which the information is transferred to the Bluetooth device, and then the program terminates in terminal 360. It can be predetermined whether the type of input is for a Bluetooth device or for a NFC device as demonstrated in FIG. 22.

With reference now to FIG. 23, there is presented a table 390 listing the type of wireless inputs and outputs to and from first wearable device 100 using either Bluetooth or NFC signals as an exemplary. In general, Bluetooth signals are used when there is a greater distance involved, such as from first wearable device 100 to a computing device 10, such as a smart phone. NFC signals are used where the distance is relatively small, such as from one first wearable device 100 to another second wearable device 100 in close proximity thereto (see FIG. 1). Table 390 shows that a GPS signal and information can be sent from first computing device 10 to first wearable device 100 and from first wearable device 100 to smart phone by a Bluetooth signal. Similarly, Bluetooth signals are sent to and received by first wearable device 100 to carry barcode and QR code information, and/or motion information detected from first wearable device 100. On the other hand, business card stored in memory unit 162 can be communicated upon command to a nearby wearable device, such as second wearable device 100 by NFC signals.

With reference now to FIG. 24, a subroutine for calculating caloric consumption is depicted. The subroutine begins at a start terminal 410 and then proceeds to a process step 412 to scan a barcode of food that a user will be ingesting. Should the computing capacity at the wearable device be limited, the computing process can be executed at computing device 10 instead of or in addition to that at first wearable device 100. The subroutine proceeds to a decision step 414 where it is determined if the user has preset first wearable device 100 to calculate the calories of the food. If the setting is preset in that way, then the subroutine proceeds to process step 416 in which a calculation of the total calories consumed is made. From step 416 the subroutine then determines in process step 418 the amount of calories burned through exercise by using information about the exercise that is stored on first wearable device 100. In process step 420, the calorie information is sent to computing device 10 in a first computing device 10. In step 422, the acti-block 214 (see FIG. 21) that contains cumulative calorie information is updated, and the subroutine ends at termination terminal 424.

If in decision step 414 it is determined that there is no setting that the calculation is executed on wearable device, then the program branches to a second decision step 426 where it is determined if a first computing device 10 is present. If it is found that there is no first computing device 10 present, then the program loops back to the top of decision step 414. If there is a first computing device 100 present, then the program proceeds to a process step 428 where a calculation of the total amount of calories of the selected food is made at first computing device 10. The program proceeds to process steps 430 and then 432 where the caloric information in the smart phone is updated, and also sent to first wearable device 100, respectively. Then before exiting the subroutine at termination terminal 570, the program updates first dependent screen 172 (See FIGS. 20A, 20B, and 20C) on first wearable device 100 in step 434.

With reference now to FIG. 25, a subroutine is disclosed to determine how much exercise a user has had. The subroutine begins in start terminal 510 and proceeds to a process step 620 where the motion of a user is recognized and a determination is made as to what type of motion it is. In the present embodiment, the motions being tracked are those of the wrist on which first wearable device 100 is being worn. But because motion of the wrist and arm of the user will be in synchronization with other motions of the body of the user, such as in running or walking, a fairly accurate determination can be made as to the type of motion being done. For example, by determining the velocity and acceleration of an arm being swung, it can be determined if the user is walking or running. Since the distance can be determined by motion detectors 118 and 119 (by double integrating the measured acceleration), and using the elapsed time, the speed of motion can be determined and the amount of calories, for example, can be determined. Thus, the program proceeds from process step 520 to a decision step 530 where it is determined if the detected motion is one of a predetermined type of motion. If it is not, then the program loops back to the top of step 520 and awaits the recognition of a motion of the user. If the detected motion is of a predetermined type, the program branches to process step 540 where a calculation of the number of motions is made. The subroutine then proceeds to process step 550 and then process step 560 where the motion information is sent to first computing device 10 where the number of steps taken are calculated and the information stored, respectively. From step 560 the subroutine terminates in termination terminal 570.

With reference now to FIGS. 26 and 27, a process of transferring social information between a first user of a wearable device (e.g. 100) to a second user of a wearable device (e.g. 200), as depicted in FIGS. 1 and 27, is depicted in the disclosed subroutine and hardware block diagram. The social information can be for example information that is contained on a business card. This would include such information as name, title, business or company name, business address, business telephone and facsimile numbers, email address, Skype name and Instant Messenger name. This information is stored in a signature barcode 114 or in wearable device memory unit 162 through an earlier input operation from first computing device 10 or other computer connection. It can also be obtained from a social media network web sites such as Facebook, Linkin, and Twitter.

The subroutine of FIG. 26 begins in start terminal 610 and proceeds to step 620 where the signature barcode 214 of second wearable device 100 (of the presumed second user) is read by the barcode scanner 113 of first wearable device 100 of the first user. Then the program proceeds to process step 630 wherein the signature barcode information is saved on first wearable device 100. From step 630, the program proceeds to a decision step 640 wherein it is determined if the computing device 10 of the first user can be found. If no first computing device 10 can be found, the program loops back to the beginning of step 630. If a first computing device 10 is detected, the program proceeds to process step 650 where the signature barcode information is sent to computing device 10 of the first user. Then the program proceeds to process step 660 wherein the barcode information is sent to the server 700 (FIG. 27). From server 700, the new “friend” is added to one or more appropriate social networks, or a network provided by the present disclosure. From step 660, the program proceeds to process step 670 and then to termination terminal 680. In process step 670 server 700 verifies and authenticates the information and adds the second smart phone user 200 to the wearable device of the friend.

The schematic of a hardware configuration that illustrates the operation of the subroutine in FIG. 26 is depicted in FIG. 27. Barcode scanner 113 of the first user reads the signature barcode 214 of the second wearable device 100 of the second user through a scanning process. First wearable device 100 is connected through a Bluetooth connection to the first computing device 10 of the first user, which in turn is connected by an internet connection (e.g. a wireless connection) to a server 700. Server 700 uploads the information to a designate web site. Obviously, server 700 is representative and could include other well known alternatives, such as cloud computing.

With reference now to FIG. 28, a subroutine that implements a level of security is depicted. The subroutine starts in start terminal 710 and proceeds to a decision step 720 where the presence of an NFC (Near Field Communications) device is determined. An NFC device is one that communicates to another NFC device using weak electromagnetic radiation and the NFC protocol over a very short distance from actual touching to a few inches. A smart phone uses NFC to communicate such information as business cards, photographs, and small files to another smart phone. If an NFC device is detected, the program branches to a second decision step 730 which inquires if the NFC device detects a predetermined signal. One such signal can be a password or predetermined gestures such as handshake. If an NFC device is not detected, the program loops back to the top of decision step 720 to await the receipt of an indication that an NFC device is present. In a similar manner, if a predetermined signal is not detected in decision step 730, the program loops back to the top of decision step 730. If a predetermined signal is detected, the program proceeds to a process step 740 where a predetermined function is performed. An example of such a function would be to check that a transmitted password is acceptable and to allow communication between the two devices. From process step 740 the program exits the subroutine through a termination terminal 750.

A multi-use for a first wearable device 100 utilizing the same or universal key or password for several different types of devices is depicted in FIG. 29. first wearable device 100 is bidirectionally connected using Bluetooth to a first computing device 10, which could in alternative embodiments also be a general purpose, programmed computer system. In addition, first wearable device 100 is bidirectionally connected using NFC, a scanner or Bluetooth to one of several types of transceivers. For example, wearable device is shown connected to a transceiver 810 that operates a door, to a transceiver 820 that controls several functions of an automobile (e.g. rolling down the windows, starting the car, or turning on the heat or air conditioner), and to a transceiver 830 that controls the operation of a copier. Thus, each of these devices can be controlled by a single wearable device code. Each of transceivers 810, 820, and 830 is bidirectionally connected using wireless network to a server 30, which is also bidirectionally connected using Bluetooth to first computing device 10. The user can use first wearable device 100 as an universal key for several different types of devices. In a case that the user lost first wearable device 100, the user can change the password for first wearable device 100 on server 30.

With reference now to FIG. 30, a subroutine for monitoring a wearable device is depicted. The subroutine begins in a start terminal 910 and immediately goes to a decision step 920 that determines the time from the last status signal to the present and determines if a signal from wearable device is more than a predetermined amount. If the minimum time since the last signal is longer than a predetermined amount, the program proceeds to a process step 930 in which computing device 10 or first wearable device 100 sends a warning signal to a server. The program then proceeds to a process step 940 in which the user's password is reset or changed, and then to termination terminal.

With reference to FIG. 31, a subroutine for voluntarily or manually changing a password is depicted. The subroutine begins in a start terminal 1010 and immediately goes to a decision step 1020 where a user has voluntarily changed a password on first computing device 10. The program then proceeds to a process step 1030 in which start phone 10 sends the changed password to first wearable device 100. From step 1030 the program proceeds to a process step 1040 in which the user is given an opportunity to display the new password in a pre-determined manner, such as a barcode or a QR code. The program then terminates in a termination terminal 1050. Thus, first wearable device 100 can display a barcode or a QR code on display assembly 130 so that the barcode scanner 213 of another second wearable device 100 can read and scan the barcode or QR code on the wearable device's 100 display assembly. According to the present disclosure, first wearable device 100 does not need to carry a physical barcode or QR code.

According to a predetermined setting, first wearable device 100 can transfer information either to another second wearable device 100 (see FIG. 1) or computing device 10. With reference now to FIG. 32, a subroutine for general procedure for operating a wearable device is depicted. The subroutine begins at a start terminal 1110 and proceeds to a step 1120 where the processor receives an input from a wrist band unit of the wearable device or a signal from a first portable network device. From step 1120, the process proceeds to a decision step 1130, where control unit 140 (FIG. 1) determines whether the input or the signal is a predetermined type. From step 1130, the process proceeds to a communication step 1140, where a network unit communicates with at least one of the first portable network devices, a second portable network device, and a server via a wireless communication channel. From step 1140, the process proceeds to a displaying step 1150, where the display assembly 130 displays a message. From step 1150, the process proceeds to end terminal 1160.
